SIDNEY A. HOOVER AND AARON LOUGHEED, OF PORT ARTHUR, CANADA.

LAM P-BURNER.

SPECIFICATION forming part of Letters Patent No. 578,875, dated March16, 1897.

Application led March 20, 1896.

T0 all whom it may concern.:

Be it known that we, SIDNEY A. HOOVER, merchant, and AARON LOUGHEED,surveyor, of Port Arthur, in the district of Thunder Bay, in theProvince of Ontario, Canada. have invented certain new and usefulImprovenientsin Lamp-Bu rn ers; and we hereby declare that the followingis a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in thatclass of lamp or lantern burners in which the wick-tube consists of asleeve extending from the bottom to the top of the oil-receptacle,fitted at the top with a suitably-supported disk to distribute the airto the dame of the wick, which passes upward through the said sleeve;and the invention consists, essentially, of the device hereinafter morefully set forth, and more particularly pointed out in the claim.

In the drawings,'Figure 1 is a perspective sectional view showing ourimprovements. Fig. 2 is a detailed view of the disk and actuatingrod.Fig. 3 is a detail view of the supporting-guides for the actuating-rod.

Like letters of reference refer to like parts throughout the specicationand drawings.

Within the bowl or oil-receptacle A is a sleeve B, which extends fromthe bottom to the top of the bowl. Surrounding the sleeve B is aperforated tube C, and interposed between the tube C and the sleeve B isa wick D. It might here be stated that the sleeve B is so arranged thata free passage of air is provided from the bottom of the bowl to the topof the burner. At the top of the sleeve B is a perforated tube E, of alesser diameter than the inner diameter of the sleeve, in order that thetube E can freely move within the sleeve. To enable the tube E tomaintain its proper relative position to the sleeve B, we provide itslower end with a flange F, which snugly fits against the inner face ofthe sleeve. The top of the tube E is iitted with a disk G, of a greaterdiameter than the outer diameter of the perforatedtube C, in order thatit will overlap the wick and said tube C. Depending from the under sideof the middle of the disk G is a pin H, the lower end H of which isscrew-threaded to receive the upper end of the actuating-rod I. The

actuating-rod I extends from the lower end i serial No. 584.114. (Nomodel.)

of the pin H to a point below the lower end of the sleeve B, and fittedtothe lower end of the rod I is a thumb-nut J, adapted to be grasped bythe operator. The upper end of the rod I is maintained in its properposition by a guide K, suitablyY connected to the rod I, while the lowerend of the rod I is held by a guide L, connected to the lower end of thesleeve B. The thumb-nut J is tted with a shoulder j, which abuts againstthe under side of the guide L and limits the upward movement of theactuating-rod. Passing diametrically through the middle of theactuating-rod is a pin M, and coiled on the actuating-rod, between theunder side of the pin 'M and the top of the guide L, is a spring N.

It has heretofore been customary to immovably fix the tube E to thesleeve B and to make the disk G of substantially the same diameter asthe inner diameter of the sleeve.

The purpose of the tube E and disk G is to distribute the air to theflame.

By rendering the tube E and disk G movable and increasing the diameterof the disk to overlap the top of the wick-tubes the disk can beutilized for the purpose of instantaneously extinguishing the flame whendrawn down ward by the ac tuating-rod, thus prevent` ing the escape ofnoxious 'carbonio gases, in addition to rendering the lamp less liableto explosion and facilitating the extinguishing of the light.

The operation of the device is as follows: When it is required toextinguish the light, the actuating-rod is drawn downward by anoperator, drawing downward atthe same time the tube E and disk G untilthe disk comes into contact with the wick and its tubes. The contact ofthe disk G at once extinguishes the flame, and immediately upon thereleasement of the actuating-rod the spring N lifts the rod until theshoulder 7' of the thumb-nut abuts against the under side of the guide Land arrests the upward movement of the actuating-rod. The thumb-nut J isso adj usted that when the upward movement of the actuating-rod isarrested the disk and the tube E will be returned to their normalposition.

Having thus fully described our invention, what weY claim as new, anddesire to secure by Letters Patent, is

A flame-extinguisher for lamps or lanterns,

IOO

eonsistin g of a bowl or oil-receptable, a sleeve within the bowl.extending from the top to the bottom, a perforated tube surrounding thesleeve to form a wick-chamber, a perforated tube within the top of thesleeve, the lower end of which is provided with a flange vbearingagainst the inner face of the sleeve,

a disk fitted to the top of the perforated tube overlapping the saidsleeve, a sorew-threaded pin depending from the under side of the disk,an actuating-rod located within the said sleeve extending below thebottom of the bowl, the upper end of which is fitted to the said pin, athumb-nut tted to the lower end of the actuating-rod, a guide connectedto the 15 bottom of the sleeve to maintain the actuatin g-rod in itsproper position, a Cross-pin fitted to the actuating-rod between theguide and the top disk, a spring coiled on the actuating-rod between thecross-pin and the said 2o
